EKI-2525 & 2528 User Manual 2

Chapter 1 Overview

1.1 Introduction

The EKI-2525/2528 is a cost-effective solution and meets the high reliability requirements demanded by industrial applications.

1.1.1 High-Speed Transmissions The EKI-2525/2528 includes a switch controller that can automatically sense transmission speeds (10/100 Mbps). The RJ-45 interface can also be auto-detected, so MDI or MDI-X is automatically selected and a crossover cable is not required. All Ethernet ports have memory buffers that support the store-and-forward mechanism. This assures that data is properly transmitted.

1.1.2 Dual Power Input EKI-2525/2528 redundant power input design is with power reserve protection to prevent the switch device broken by wrong power wiring. When one of power input is fail, P-Fail LED will turn on and send an alarm through a relay output for notifying user.

1.1.3 Flexible Mounting EKI-2525/2528 is extremely compact (37 x 140 x 95 mm) and can be mounted on a DIN-rail or a panel, so it is suitable for any space-constrained environment.

1.1.4 Advanced Protection EKI-2525/2528 supports up to 3,000 VDC surge protection for power line, and also supports 4000V ESD for Ethernet ports. With these 2 strong protections, it can secure equipment against unregulated voltage and make systems safer and more reliable. Further, EKI-2525/2528 provides currency overload protection with a resettable fuse to ensure that the device component won’t be damaged by overload current.

1.1.5 Wide Operating Temperature The operating temperature of the EKI-2525/2528 is between -10 ~ 60 . With such a wide range, you can use the EKI-2525/2528 in some of the harshest industrial environments that exist.

1.1.6 Easy Troubleshooting LED indicators make troubleshooting quick and easy. Each 10/100 Base-TX port has 2 LEDs that display the link status, transmission speed and collision status. Also the three power indicators P1, P2 and P-Fail help you diagnose immediately.

LED Color Description

On Power input 1 is active P1 Green

Off Power input 1 is inactive

On Power input 2 is active P2 Green

Off Power input 2 is inactive

On Power input 1 or 2 is inactive P-Fail Red

Off Power input 1 and 2 are both active, or no power input

On Connected to network

Flashing Networking is active Link/Active (1~5 or 1~8) Green

2.3 Mounting

The EKI-2525/2528 supports two mounting methods: DIN-rail & Wall. 2.3.1 Wall mounting EKI-2525/2528 can be wall-mounted by using the included mounting kit. Then, hang on the EKI-2525/2528 to the nails on the wall. First, use the screws included in the package to combine the EKI-2525/2528 and metal mounting kit. And then you can install the device firmly via the components, please see Figure 2.5 as below.

Figure 2.5: Combine the Metal Mounting Kit


2.3.2 DIN-rail Mounting You can also mount EKI-2525/2528 on a standard DIN-rail by below steps. The DIN-rail kit is screwed on the industrial switch when out of factory. If the DIN-rail kit is not screwed on the industrial switch, please screw the DIN-rail kit on the switch first. First, hang the EKI-2525/2528 to the DIN-rail with angle of inclination. See figure 2.6.

Figure 2.6: Installation to DIN-rail Step 1

15 Chapter2

Then, let the device down straight to slide over the rail smoothly. See Figure 2.7

Figure 2.7: Installation to DIN-rail Step 2


2.4 Network Connection

The EKI-2525 has 5 x RJ-45 ports or EKI-2528 has 8 x RJ-45 ports that support connection to 10 Mbps Ethernet, or 100 Mbps Fast Ethernet, and half or full duplex operation. EKI-2525/2528 can be connected to other hubs or switches through a twisted-pair straight through the cable or a crossover cable up to 100m long. The connection can be made from any TX port of the EKI-2525/2528 (MDI-X) to another hub or switch either MDI-X or uplink MDI port. The EKI-2525/2528 supports auto-crossover to make networking more easy and flexible. You can connect any RJ-45 (MDI-X) station port on the switch to any device such as a switch, bridge or router.

2.5 Power Connection

The EKI-2525/2528 supports dual +12 ~ 48 VDC power inputs and power-fail relay output.

Figure 2.8: Pin Assignment of the Power Connector

You can connect an alarm indicator, buzzer or other signaling equipment through the relay output. The relay opens if power input 1 or 2 fails ( “Open” means if you connect relay output with an LED, the light would be off).

TER


Chapter 3 Troubleshooting 1. Power Input Verify that is using the right power cord/adapter (+12~48 VDC), please don’t use the power adaptor with DC output voltage higher than 48V, or it will burn this converter down. 2. Cable Select the proper UTP cable to construct user network. Please check that is using the right cable. Use Unshielded Twisted-Pair (UTP) or Shielded Twisted-Pair (STP) cable for RJ-45 connections: 100 Category 3, 4 or 5 cable for 10 Mbps connections or 100 Category 5 cable for 100 Mbps connections. Also, be sure that the length of any twisted-pair connection does not exceed 100 meters (328 feet). 3. Diagnosing LED Indicators The switch can be easily monitored through panel indicators, which describes common problems user may encounter and where user can find possible solutions, to assist in identifying. If the power indicator does not light up when the power cord is plugged in, user may have a problem with power cord. Then check for loose power connections, power losses or surges at power outlet. If user still cannot resolve the problem, contact the local dealer for assistance. If the Industrial switch LED indicators are normal and the connected cables are correct but the packets still cannot transmit, please check your system’s Ethernet devices configuration or status.
